Jacksonville plumbing questions
How do I verify a plumber in Jacksonville?
Check the license on MyFloridaLicense.com. A certified plumbing contractor (license code starting with C) can work anywhere in Florida.
Why do slab leaks happen in Jacksonville homes?
Most homes sit on concrete slabs with copper or plastic water lines underneath. Abrasion, corrosion and ground movement can open a leak you can't see, and the usual signs are a warm spot on the floor, the sound of running water, or a meter that keeps moving. See slab leak repair.
What should I do about plumbing before a hurricane?
Know where your main shutoff is, have backflow and sump devices checked, and after the storm watch for sewer backups and leaks from shifted pipes. See emergency plumbing.
